Ignore bitrate buffer underflows. If the encoder uses so many bits that

.P
Don't bank excess bits for later use
.P
Ignore bitrate buffer overflows. If the encoder uses so few bits that
the reservoir of available bits overflows, ignore the excess. The
encoder will not try to use these extra bits in future frames. At high
rates this may cause the result to be undersized, but allows a client to
play the stream using a finite buffer; it should normally be enabled.

.P
.BR cap_underflow "=[1|0] (default: 0)"
.P
Don't try to make up shortfalls later
.P
Ignore bitrate buffer underflows. If the encoder uses so many bits that
the reservoir of available bits underflows, ignore the deficit. The
encoder will not try to make up these extra bits in future frames. At
low rates this may cause the result to be oversized; it should normally
be disabled.

.P
.BR speed "=<number> (0.00..1.00, default: 0.00)"

Encoding speed
.P
Higher speed levels favor quicker encoding over better quality per bit.
Depending on the encoding mode, and the internal algorithms used,
quality may actually improve, but in this case bitrate will also likely
increase. In any case, overall rate/distortion performance will probably
decrease.
